' COMPOUND RAIL. 1

Specification of Letters Patent.

Patented Sept. 16, 1913.

Applicati on filed July 6, 1912. Serial No. 707,987.

To all whom it may concern:

Be it known that I, ED\VARD P. CALDWELL, a citizen of the United States, residing at Waterloo, in the county of Blackhawk and State of Io-wa,have invented new and useful Improvements in Compound Rails, of which the following is a specification.

This invention relates to certain new and useful improvements in compound rails,and the object thereof is to; provide a rail in which the head is separable from the base andis connected thereto by improved means of efficient and Simple character.

In the drawings: Figure 1 is a vertical sectional view of a rail constructed in accordanoe with the present invention; Fig. 2 is a fragmentary perspective view of the head of the rail; Fig. 3 is a similar view of th fish plate; Fig. 4 is a vertical sectional view of a modified form of the invention; Fig. 5 is a fragmentary perspective view of the rail head shown in Fig. 4; and Fig. 6 is a similar view of the fish plate of Fig. 4.

In proceeding in accordance with the present invent-ion, a base 1 is provided with a web portion 2, while the head 3 is provided with a depending web portion 4 which is enlarged and provided with a longitudinal slot 5 of U-shape in cross section. The web portion 4 is provided with a cut-out part 6 which forms a seat 7 and a depending flange 8, which seat and flange are engaged by the upper edge and one side re spectively of the web portion 2 of the base 1. The side of the web portion 4 that has the longitudinal slot 5 therein extends flush with the opposite side of the web portion 2 of base 1. A fish plate 9 is provided with a'right angular flange 10 that is conformably received in the slot 5 of the web ortion 4, the inner side face of the fish p ate 9 being in contacting engagement with the alining sides of the web portions 2 and 4. Bolts 11 equipped with nuts 12 are passed through registering perforations provided therefor in the flange 8, web port-ion 2, and fish plate 9, whereby upon tightening of the nut, the flange 8 and the fish plate 9 will be drawn into binding engagement with opposite sides of the web portion 2 and the side of web portion 4 that is formed with the slot 5.

In the modified form of the invention depicted in Figs. 4, 5 and 6, the parts are constructed identically as above described, with the exception that the slot 5' is formed with a depressed part 5 and the fish plate 9 is formed with a hook or bill shaped flange 10 which is adapted to conformably engage in the slot ,5 and its depressed part 5, forming a hook engagement between the fish plate and the web portion of the head 3.

From the above it will be seen that. the head andthe base portions of the rail are rigidly and effectively united, and that the parts can be easily and quickly separated and assembled for the purpose of removing a worn or damaged head or base and replacing the same with a new one. The flanges of the fish plate not only strengthen the latter, but in addition serve to resist the strain that the car wheel W' in riding on the rail head impart-s thereto.

What is claimed is:

1. In a rail, a base having a web portion, a head having an enlarged depending web portion and formed with a seat that engages the upper edge of the base web portion and having a depending flange at one side of the seat that engages a side of the base web portion, the head web portion being formed with a longitudinal slot 011 the opposite side of the seat thereof and above the upper edge of the base web portion, a fish plate abutting the opposite side of the base web portion and the side of the head web portion that has said slot therein, said fish plate extending across the joint between the base web portion and the head web portion being formed with a flange that extends in the slot of the head web portion, and bolts passed through the flange of the head web portion, the web portion of the base and the fish plate.

2. A rail composed of a base portion having a web, a head portion having a web that seats on the upper edge of the base web portion and formed with an extension that engages a side of the base web portion, and a flanged fish plate engaging the opposite side of the base web portion and being secured to the latter and having the flange thereof received in a slot provided therefor in the web portion of the head.

3. In a rail, a base having a web portion and a head having a web portion that seats on the upper edge of the web portion of the base, means integral with one of the web portions to engage the other, and removable means secured to one of the web portions and engaging both of the web portions.

4. In a rail, a base having a web portion and a head having a Web portion that seats on the upper edge of the Web portion of the base, means integral with one of the iveb portions to engage the other, and removable means secured to one of the Web portions and having a projection that extends into a slot provided therefor in the other Web portion.

5. In a rail, :1 base and a head having contacting Web portions, and a removable fish plate secured to one Web portion and having inter-engagement With the other.

6. In a rail, :1 base having a Web portion, a head having a Web portion that seats on the upper edge of the base Web portion and Copies of this patent may be obtained for an cents each; by addressing the domiilissioiier of Patents,

has one side thereof flush with the adjacent side of the base \veb portion, said head Web ortion havin' an extension which en 'a es P a; a g g the opposite side of the base Web portion, and a removable fish plate secured to' the base web portion and extending across the joint between the head Web portion and the base We'b portion. 7
